As I understand it, all EISA boards suffer from this problem. >That's why I'm trying to get this VLB card to work. This is incorrect. ISA (the "standard" IBM-AT 16-bit bus) will only support up to 16meg of RAM. EISA is a 32-bit bus-mastered bus, which is actually more robust than VLB in many respects. EISA supports 32-bit addressing the same as VLB does, which means EISA and VLB will support theoretically up to 4gigabytes of RAM (in practice this is less because of physical limitations such as number of SIMM sockets and such things). -- ------------------------------------------------------------------------------ Michael L.
